Abstract

In this project new concept is proposed which is fault current limiting DVR. Fault is detected by sensing the load current and its rate of change. In order to protect the sensitive equipment fault current is limited such that life of the equipment and the quality of the supply is improved. Bidirectional thyristor switches are used on the output side of PCC to limit the fault current. Switches are activated under fault condition and de-activated under normal condition. This is modeled using MATLAB SIMULINK.

一种限制配电系统故障电流的拓扑结构
本课题提出了故障限流DVR的新概念。通过感应负载电流及其变化率来检测故障。为了保护敏感设备,限制故障电流,从而提高设备的使用寿命和供电质量。PCC的输出端采用双向晶闸管开关来限制故障电流。开关在故障状态下激活,在正常状态下关闭。利用MATLAB SIMULINK对其进行建模。
